Real life results from prototype 2100V 50/50 Ar/CO2 with scintillators horizontal, cosmics not limited to 90^o
Drift time (- offset) in ns	First max in signal amplitude	Integrated signal

Garfield for 3GeV muons at 90^o to straw
Drift time (- offset)	First max in signal amplitude	Integrated signal

Garfield for 400MeV/c protons at 45^o to straw
Drift time (- offset)	First max in signal amplitude	Integrated signal

Garfield for 400MeV/c protons at 23^o to straw
Drift time (- offset)	First max in signal amplitude	Integrated signal

Same prototype run, lower hit threshold (3sigma) 2100V 50/50 Ar/CO2
Max amp	Integrated signal	Integrated signal for hits with maxamp < 90
Integrated signal for hits with maxamp < 60
